Those are nowhere near the strength of medieval military longbows. At max those would be 22 kils (48 pounds) for men, and 17 kilos (38 pounds) for women. A full strength English military longbow built to penetrate heavy plate armor typically had a draw weight almost matching a man's average weight of the time, between 130-190 lb draw weight. Something of this strength makes a much different sound to the competition bows in the linked video.
